20120068368 | METHOD FOR MANUFACTURING OPTICAL DIFFRACTION ELEMENT - If an optical lens base having a diffraction grating on the surface is made of a resin, a corrosion reaction is produced between the optical lens base and a nanocomposite film material, thus deteriorating performance as a diffractive optical element. In the manufacturing process of a diffractive optical element according to the present invention, the nanocomposite film material is dripped onto a die and then heated and dried, thereby vaporizing away a solvent from the nanocomposite film material. After that, the dies are assembled to form a nanocomposite film with a predetermined thickness on the optical lens base. As a result, a diffractive optical element with excellent optical properties can be obtained without producing a reaction between the optical lens base and the nanocomposite film material. | 03-22-2012 |
